Finding Stop IDs

Stops are identified by RBL numbers (Rechnergestütztes Betriebsleitsystem). Use the reference data:

# Search stops by name
curl -s "https://www.wienerlinien.at/ogd_realtime/doku/ogd/wienerlinien-ogd-haltepunkte.csv" | grep -i "stephansplatz"

# Format: StopID;DIVA;StopText;Municipality;MunicipalityID;Longitude;Latitude

Common Stop IDs (RBL):

Stop	RBL IDs	Lines
Stephansplatz	252, 4116, 4119	U1, U3
Karlsplatz	143, 144, 4101, 4102	U1, U2, U4
Westbahnhof	1346, 1350, 1368	U3, U6
Praterstern	4205, 4210	U1, U2
Schwedenplatz	1489, 1490, 4103	U1, U4

Common Use Cases

"When is the next U1 from Stephansplatz?"

# Stephansplatz U1 platform RBL: 4116
curl -s "https://www.wienerlinien.at/ogd_realtime/monitor?stopId=4116" | jq '.data.monitors[].lines[] | select(.name=="U1") | {line: .name, towards: .towards, departures: [.departures.departure[].departureTime.countdown]}'

"Are there any U-Bahn disruptions?"

curl -s "https://www.wienerlinien.at/ogd_realtime/trafficInfoList?relatedLine=U1&relatedLine=U2&relatedLine=U3&relatedLine=U4&relatedLine=U6" | jq '.data.trafficInfos[] | {title, description, lines: .relatedLines}'

"Which elevators are out of service?"

curl -s "https://www.wienerlinien.at/ogd_realtime/trafficInfoList?name=aufzugsinfo" | jq '.data.trafficInfos[] | {station: .attributes.station, location: .attributes.location, status: .attributes.status}'

"Departures from Karlsplatz with all disruption info"

Tips

1. Multiple platforms: A single station may have multiple RBL IDs (one per platform/direction). Query all for complete departures.

2. Real-time availability: Check realtimeSupported - some lines only have scheduled times.

3. Countdown vs timeReal: Use countdown for display, timeReal for precise timing.

4. Barrier-free routing: Filter by barrierFree: true for wheelchair users.

5. Find stop IDs: Search the CSV files by station name, then use the StopID as stopId parameter.

Wiener Linien Skill

A skill for querying Vienna's public transport (Wiener Linien) real-time data including departures, disruptions, and elevator status.

Overview

This skill provides tools to access Wiener Linien's real-time API for:

• Real-time departures at any stop
• Service disruptions (short-term and long-term)
• Elevator outages at U-Bahn stations
• Stop search by name to find RBL stop IDs

Scripts

search-stop.sh - Find Stop IDs

Search for stops by name to get their RBL (stop) IDs needed for departure queries.

./search-stop.sh stephansplatz
./search-stop.sh kagran

departures.sh - Real-Time Departures

Get next departures from one or more stops. Supports multiple stop IDs for stations with multiple platforms.

./departures.sh 252              # Single stop
./departures.sh 252 4116 4119    # Multiple platforms (Stephansplatz)

disruptions.sh - Service Disruptions

Get current disruptions, optionally filtered by line.

./disruptions.sh                 # All disruptions
./disruptions.sh U1 U3           # Only U1 and U3
./disruptions.sh 27A             # Specific bus line

elevators.sh - Elevator Outages

Get elevator outages at stations, optionally filtered by line.

./elevators.sh                   # All elevator outages
./elevators.sh U6                # U6 stations only

Common Stop IDs (RBL)

Stop	RBL IDs	Lines
Stephansplatz	252, 4116, 4119	U1, U3
Karlsplatz	143, 144, 4101, 4102	U1, U2, U4
Westbahnhof	1346, 1350, 1368	U3, U6
Praterstern	4205, 4210	U1, U2
